Benefits of technology

"The invention is a system for monitoring the connection between a lug stud and a lug nut on a vehicle wheel. The system includes a lug stud with a sensor attached to it, a lug nut that fastens onto the lug stud, and an indicator that communicates with the sensor. The sensor measures various conditions between the lug stud and lug nut, and the indicator alerts the operator of the vehicle when a predetermined reference value is reached. The system can also include a radio frequency transmitter and a radio frequency receiver, a control module, a display, and a power source. The technical effects of the invention include improved monitoring of the connection between the lug stud and lug nut, which can help prevent accidents and reduce maintenance costs."

Problems solved by technology

Sometimes the lug nuts come loose; sometimes they were never properly tightened to begin with; or sometimes they are too tight.

Embodiment Construction

[0015]Referring now to the drawings, FIGS. 1-4 show example embodiments of a lug stud and lug nut monitoring system and method, generally shown at 10, that monitors each lug stud, generally indicated at 12, and each lug nut, generally indicated at 14. The monitoring system 10 can, in some cases, detect a torque between the lug stud 12 and the lug nut 14 and can remotely alert an operator of the associated vehicle if the lug nut is undertorqued (e.g., loose or not torqued enough) and if the lug nut is overtorqued (e.g., torqued too much). The monitoring system 10 may be equipped as original equipment or retrofitted on all vehicle wheels 16 of an automobile, a semi-truck, or the like. In one example embodiment, the monitoring system 10 may include the lug stud 12, the lug nut 14, a sensor 18, an indicator, and a power source 40.

[0016]A plurality of lug studs 12 is used with the lug nuts 14 to mount the vehicle wheel 16 on the associated vehicle hub. Referring to FIG. 2, an example lug...

Abstract

A lug stud and lug nut monitoring system, method, and components for a vehicle may have a lug stud, a lug nut, at least one sensor, and an indicator. The lug stud has a shank. The lug nut is constructed to fasten on the shank. The sensor can be carried by the lug stud, by the lug nut, or by both the lug stud and the lug nut. The sensor takes at least one measurement. The indicator communicates with the sensor in order to determine a value based on the measurement, and to alert an operator of the vehicle if and when the value reaches a predetermined relationship to a reference value.

Description

TECHNICAL FIELD[0001]The subject invention generally relates to vehicle wheels, and more particularly to systems, methods, and components used to monitor lug studs and lug nuts.BACKGROUND[0002]Vehicle wheel rims are commonly mounted to a hub by lug nuts fastened down on an equal number of lug studs. Sometimes the lug nuts come loose; sometimes they were never properly tightened to begin with; or sometimes they are too tight. Having a way to remotely alert a driver of these conditions may be helpful.SUMMARY OF THE INVENTION[0003]According to one conception of the invention, a vehicle lug stud and lug nut monitoring system may include a lug stud, a lug nut, at least one sensor, and an indicator. The lug stud has a shank. The lug nut is constructed to fasten on the shank. The sensor is carried by the lug stud, by the lug nut, or by both the lug stud and the lug nut. The sensor takes at least one measurement. The indicator communicates with the sensor in order to determine a value that ...
